“Don’t copy, use how to, mauals…” hmm so I am not supposed to use PIE concept, because it is kind of how to.
And what is wrong with “best regards” I use frequently at the end of my email. What is a substitute for it, I know I can write down “with respect” but it feels the same and I haven’t came up with something better…yet 🙂

You are not supposed to do anything -> do whatever feels right for you, which is very much said: in call for authenticity repeated many times in the video. Plus believe me that starting any new interactions with genuine praise of the receiver – shows your interest in the person and her work/art.
Best regards,
